When selecting bearings for heavy machinery, mining equipment, or precision automotive systems, the choice of steel is not a trivial detail\u2014it defines the service life, reliability, and maintenance costs of the entire assembly. Two materials that often come up in technical discussions are SKF3 and GCr15. Both are high-carbon chromium steels, but their performance can diverge significantly depending on the operating environment. SKF3 is a proprietary grade developed by SKF, engineered for enhanced fatigue resistance and microstructural cleanliness. GCr15, on the other hand, is a widely adopted Chinese standard (equivalent to AISI 52100 or 100Cr6) that has [&hellip;]"}
